Leader Instruments Corporations heads to the Las Vegas Convention Center in April for the 2017 NAB Show. Centrepiece of the demonstration on booth C9021 in the Central Hall will be the latest additions to the LV5490 multiscreen waveform monitor. Occupying a half-rack-width by 4U high housing, the Leader LV5490 offers 4K, UHD, 3G, HD and SD test and measurement features in a compact portable unit. Waveform, vector, five-bar and picture display can all be viewed at the same time on the LV5490's 9 inch LCD monitor.
The monitor is full 1920 x 1080 HD resolution with a wide viewing angle and high colour reproduction. A 1920 x 1080 HD DVI and HD-SDI rasterized output is also provided to feed a larger monitor. Simultaneous viewing of up to four SDI inputs is possible, including overlays. The size and location of individual channels can be adjusted on the display using a USB mouse so the user is not limited to fixed-size quadrants.
The LV5490SER07 HDR option enables the LV5490 to measure both 4K and HD HDR in ITU.BT.2100 Hybrid Log Gamma, Dolby PQ or Sony SLOG-3 protocols. With the latest software, version 3.2, the LV5490 now incorporates five-bar display capabilities. Incoming SDI signals are converted into five cyan bargraphs providing simultaneous display of maximum and minimum luminance, red-component, green-component, blue-component and composite levels. Gamut errors are displayed as red excursions beyond the legal thresholds.
In its multiscreen mode, the LV5490 can display five-bar and additional user-selected reference content such as R, G and B waveforms on its internal monitor or rasterized output.
Leader's CINELITE® II toolset (comprising CINELITE and CINEZONE) also comes as a standard feature, allowing easy assessment of relative exposure and overall luminance during production. A focus assist option allows highly accurate on-set adjustment of camera focus to match the 4K format's ability to handle very precise image detail.
